To all whom it may concern: v v

Be it known that I, BENJAMIN DENVER CorrAoE, a resident of -Wilmington, Delaware (whose post-oflice address is care of The iPusey & Jones Company, Wilmington, Delaware,) have invented a new and useful Improvement in Save-All Boxes, whlch 1nvention is fully set forth in the following specification. 1

The present invention is'an improvement in save-all boxes for use under a Fourdrinier wire of a pa er-making machine, the function of these oxes being to catch water and stock. This water and stock are recovered and utilized, and hence it is necessary that the boxes should be of non-rusting material, as rust would be ruinous to the paper. For a long time these boxes have been made of wood, and in recent years some have been made of metal. It is necessary that these boxes should be light enough in weight to be manually handled, as it is necessary to remove them when removing or replacing a Fourdrinier wire, and it has been experienced that, in modern paper-makin machines capable of producing paper 200 lnches or more in width, the old wooden save-alls as well as the metal save-alls heretofore proposed are commercially impracticable, due to the weakness of the boxes which caused them to collapse under the weight of the body of water and stock collected.

Under these conditions the necessity for a light, strong, durable save-all became acute and the object of'the present inven-- tion is to provide a device which will answer these requirements, which can be readily put in place under the wire and removed manually, and which at the same time can be filled to overflowing, while being supported only at its extreme ends, without danger of collapsing.

It has been observed that, in connection with save-ails heretofore employed, and which were provided with flat bottoms and vertical sides, the sides of the box fall either in or out when the box collapses; and while cross-bracing helped somewhat, it did not provide a complete remedy for the difiiculty inasmuch as the great weight of the water would cause the sides to collapse between the braces.

More specifically, then, the present inven-' tion provides a light and strong receptacle, the sides of which are so constructed as to prevent collapse under any of the conditions encountered in actual, commercial use.

The invention willbe better understood by reference to the accompanying drawings, wherein- Figure 1 is a perspective view of a saveall box constructed in accordance with the invention; Fig. 2 is a transverse section on the line 2-2 of Fig. 1; and Figs. 3 and 4. are views similar to Fig. 2 of slightly modified forms. l

Referring to the'drawings, wherein like reference numerals indicate like parts, 5 is the front stand or support for one end of the save-all and 6 is the other stand or support for the other end. The front stand is provided with a roller 7 in order to facilitate the removal of the save-all from under the Fourdrinier wire. The bottom 8 of the save-all, which is preferably formed (bf a long strip or late of brass or other compositlon, is suita ly secured to the sides thereof. As here shown each side of the save-all is composed of two strips or plates 9 and 10, preferably of the same material as the bottom 8, said strips or plates being angularly arranged with relation to each other and, as here shown, being secured to the bottom 8 by a row of rivets 11. Preferably each of the outer plates 9 has a substantially right angle bend therein and the two longitudinal extremities of each inner plate 10 are bent so that the lower extremity 10 is parallel with the horizontal part of said outer plate 9 and the upper extremity 10 is" parallel with the vertical part of said plate 9. In order to secure the maximum strength of connection between the side plates 9 and 10 and the bottom 8, each longitudinal edge of the latter projects between extremity l0 and' the horizontal part of the outer plate, the rivets 11 passing through said extremities, the bottom 8 and said horizontal parts, thus securing the bottom and sides fixedly together. This connection between the sides and bottom renders it practically impossible to accidentally separate the parts or rup-- ture the union. The upper edges of the sides 9 and 10 are also suitably fastened together andthe structure endowed with greater rigidity by suitable connecting means,as rivets 12, and there is preferably secured between each extremity 10 and the vertical part of the outer plate 9 one member of a metallic angle piece 13, said piece being preferably secured in position in the same way that the bottom 8 is fastened to the sides, the presence of these angle pieces materially adding to the rigidity of the structure.

One end of the save-all is closed by an end-piece 14, which is suitably secured in place and which is of suitable construction. A s herein shown this end-piece is provided g at its top with n angle-Piece Bracing members 16 and 17 assist securing said endjpiece to the sidewalls of the save-all. Be-

. be stron tween said side walls are carried a plurality of transverse braces 18 provided with end f'flanges '19, the whole being preferably se- I cured in place by rivets 20. In the commercial boxes all of the braces 18'are made of light brass tubing except the one, 18, nearest the closed end-piece 14:, which ismade much heavier for withstanding the stress of the porter-bar, which is the tool used by the workmen in removing the save-all from stands 5 and 6. To remove the save-all box oneend of the porter-bar is placed overthe end.14= of the box and under said brace 18.

By then bearing down on the other end of the barthe farther end of the save-all is elevated from its stand and the whole weight rests on the roller 7 The box at this time is free from water and can be readily and easily'removed from under the wire.-

As illustrated, the end of the box opposite that which is closed by end-piece 18 is left open and unobstructed. The water runs out I of this openend into a common drain, and it is not at all unusual, when the drainage is not in good condition, for the. water toback up until the save-all is full to overflowing.

By the present construction the walls and bottom of a save-allbox, 200 inches or more in length, may be made of sheet brass less than one-sixteenth of an inch thick and yet an inde ite period, the weight'of such an overflowing volume of water, the box at the same timebeing light enough to permit of manual removal from under the wire.

The constructions shown in Figs. 3 and'4:

.are identical with the construction of Figs. I 1 and 2, except thatin Fig. 3 the angle piece is omitted and the vertical part of each outer wall 9 and the extremities 10 are riveted directly together. The same construction is "formed in Fig. 4 except that the inner member 10 is provlded with an extension 21 which on the.open market. The use of shorter,

wider strips would necessitate cross-seams whlch are very ob ect1onable on account of and rigid enough to sustain, for

. the plates on both sides thereof.

their weakness and added weight-all of which is avoided by the construction described. l

The triangular space between the side plates 9 and 10 is preferably open to the atmosphere. Each outer plate 9 is preferably continuous and imperforate throughoutits length, as a stronger and more rigid structure is thereby obtained. Any break in these outer bracing plates 9 directly affects the strength and rigidity of the structure as a Whole and, as before stated, these walls are therefore preferably imperforate.

While for the purpose of illustration several expressions of the inventive idea are herein shown and described in detail, it is to be understood that the invention is not limited to the constructions shown, but that the inventive idea is susceptible of Various mechanical expressions within the limits of the appended claims.
